Answer:
51.34 %
Explanation:
You first need to calculate the theoretical yield of Bromobutane taking into account the amount of initial Butanol doing some stoichiometric calculations:
Then you calculate the yield giving the real amount you produced:
Answer:
nitrogen is the answer because of the same position of group in periodic table
Answer:
They are moving in Brownian motion.
Explanation:
Soot particles are colloid with each other and also in gas molecules with which they are suspected. This collision provide the energy and particles moves in Brownian motion.
Brownian motion:
It is the rapid random motion of the particles result from the collision with the molecules of medium with which they are suspected.
It is the irregular or zigzag motion of soot, smoke or pollen particles.
It was first represented by Robert Brown in 1827. He put the drop of water in pollen grain and noticed through the microscope that particles are moving in up and down way. Later same type of motion was observed in case of smoke,soot and dust particles.
This motion was named as Brownian motion but Brownian could not explain this motion.
(3) the water to the ice cubes
This is so because the ice cubes are colder compared to their surrounding objects.
They absorb the heat from the water, cooling it, therefore vanishing(melting).
Another way to put it would be
The answer is (3) the water to ice cubes.
As the ice cubes should be at a temperature of about 0 degree ( freezing point) , at the same time the temperature of water is 24 degree. Thus, heat is transferred from water to ice cubes.
Answer: CO2x+O4H I don’t know if this is the right answer
